The fraternity had been on interim suspension since Nov. 3 after allegations emerged of drug use and possible hazing among members. LSU officials said the investigation stems from an Oct. 17's off-campus incident when Sigma Chi member Sawyer Reed, 21, died of an overdose. Evidence found at Reed's home led LSU officials to the fraternity house and surveillance videos of activities there.

WAFB reports the video footage shows multiple incidents of drug usage. The fraternity also suspended 66 of its 150 members after they refused to take drug tests.

Neither the university nor the national fraternity has confirmed the actions that led to the fraternity's closure.

LSU said it supports the actions of the international body to close the fraternity.

"LSU has a long standing relationship with Sigma Chi, and it's unfortunate that this is the end result, but we take any and all reports of incidents seriously and will not tolerate policy violations when it involves the health, safety and well-being of our students," said Kurt Kepler, LSU vice president for student life and enrollment.
